乌拉圭牛地方流行性白血病传入风险分析

Import Risk Analysis of Enzootic Bovine Leukosis from Uruguay into China

为评估乌拉圭牛地方流行性白血病(enzootic bovine leukosis,EBL)传入我国的风险,根据世界动物卫生组织(OIE)传入风险分析基本原理,从入境评估、暴露评估及后果评估三方面,对从乌拉圭传入EBL的风险进行分析。结果显示:从乌拉圭进口活牛、牛精液/胚胎、牛乳制品传入释放牛白血病病毒(bovine leukemia virus,BLV)的风险为“低”,暴露风险为“轻微”,传入后果为“中”,综合评估为“非常低”。根据评估结果,建议采取进口前追溯进口牛原牛场3年内EBL流行史,严格执行产地预检,进行临床检查和兽医卫生条件检查,进口后隔离检疫等风险管理措施,以有效控制EBL的传入。

In order to assess the risk of enzootic bovine leukosis(EBL)possibly introduced into China from Uruguay,the import risk was evaluated from the aspects of entry assessment,exposure assessment and consequence assessment according to the general principles of import risk analysis of OIE.The results showed that the risk of introduction and release of bovine leukemia virus(BLV)via live cattle,bovine semen,embryos and milk products imported from Uruguay was low,the risk of BLV exposure was slight,entry consequence was medium and it was concluded as very low through comprehensive evaluation.Based on the above results,it was suggested to trace the history of EBL in source farms within 3 years prior to import,and strictly implement risk management measures including pre-inspection at the place of origin,clinical examination,inspection of veterinary health conditions,animal quarantine after import,etc.,with a view to effectively controlling the introduction of EBLV.
